. 3` Clai'ms; The present invention relates to door stops and more particularly to a saf'ety device for limiting the distance a doorl orother closurel may be opened.v

Among the objects of the present invention is.

to provide a doorv stop construction which may be readily adjusted or moved to operative or inoperative position.

Another object of the present invention is the provision of a safety device adapted to permit the door or other closure to be opened a limited amount but whereby to prevent access therethrough.

A further object is to provide a door stop com'- prising a part pivotally or adjustably mounted on the fioor and a part mounted adjacent the bottom of the door or other closure.

A still further object is the provision of a safety stop for limiting the opening of a door or other closure in which the stop is so positioned and arranged that it cannot be withdrawn or replaced from the exterior, and when the door is opened thereover cannot be withdrawn until the door` is again moved to closed position.

Further objects are to provide a construction of maximum simplicity, efiiciency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear, and as are inherently possessed thereby.

The invention further resides in the combination, constructtion and arrangements of parts illustrated in the accompanying drawing, and while there is shown therein a preferred embodiment, it is to be understood that the same is susceptible of modification and change and comprehends other arrangements and details, without departing from the spirit of the invention.

In the drawing:

Fig. 1 is a fragmentary View in perspective of a door and frame therefor, and showing the position and relation of the door stop parts when the door is in closed position and the stop member is in its inoperative position;

Fig. 2 is an enlarged fragmentary view in perspective of the door at the limit of its open position;

Fig. 3 is an enlarged perspective View of the stop member;

Fig. 4 is an enlarged perspective view of the plate which is adapted to. be mounted on the door or other closure;

Fig. 5 is a view in perspective of an alternate construction of the door stop.

Referring more in particular to the disclosure in the drawing, the invention comprises a member I provided with a base 2 having its one end bent upwardly as at 3,,and its other end provided with an openingv 4 adapted to receive a. screw, bolt or the like 5 for pivotally mounting thebase: 5 member upon the floor.

Mounted on or formed integrally with the base member is provided a rib or track 6 which has at its one end a projection or strike 1 and is tapered at its other end as at 8. 10

Mounted adjacent an edge of the door and extending beyond the bottom thereof is provided a plate 9 having at its lower end a cut-out portion or notch l. Any suitable retaining means such as screws or the like ll securely hold this plate in position on the door or other closure |2.

The stop member I is pivotally mounted at 5 so as to be moved into or out of operative position or alignment with the door or other closure. When in the full line position shown in Fig. 1, this member extends alongside the door jamb and wall where it is out of the way and not liable to be tripped over. If desired, the woodwork or baseboard may be cut away so that at least a part of the stop member may project thereunder when it is in inoperative position. When it is desired to place the member in position for use, it is moved into the dotted line position shown in Fig. l in which it is in alignment with the door and plate 9. When in this position, the notch or cut-out portion will ride over the rib or track until the plate impinges against the projection or strike l when the door is open to the limit of its position. When in this position, the stop member cannot be moved because of the projections |3 on the plate 9. 'I'hus in order toagain move the stop member to a position out of use, it is necessary that the door be again closed. The tapered end 8 of the rib or track assists in `aligning the plate 9 and stop member 40 and thus it is not necessary that the latter be placed in perfect alignment when moved into a position for limiting the opening of the .door or closure.

In Fig. 5 is disclosed an alternate construction of stop member in which the base I 4 thereof is pivotally mounted as at 5 and the rib or track is made of Sections l5 and |6 suitably hinged together as at l'l, the section |6 being provided with a projection or strike I8. This hinged construction permits the stop member to be moved out of the way when the same is installed adjacent a corner of the wall where sufficient room is not available for a member made of one piece.

If desired the baseboard or the like may be cut 2 away to at least partially receive and hide the stop member.

From the above description and the disclosure in the drawing, it will be readily apparent that I have provided a. novel stop construction for doors or other closures, that numerous changes may be made in the structure and arrangement, and that the embodiment disclosed is but one form or arrangement of parts for carrying out the novel invention.

Having thus disclosed the invention, I claim:

1. A door stop for preventing the opening of a door or other closure beyond a limited amount not sufficient to permit a person to enter therethrough, comprising a member positioned on the fioor adjacent the bottom of the door and provided with a rib and projection at the end thereof, and a plate mounted on the inner side of the door adjacent its bottom and provided with a notch, the notch in said plate receiving and guiding the rib as the door is opened and moved over said member and the plate engaging the pro- `jection whereby to limit the opening of the door.

2. A door stop for preventing the opening of a door or other closure beyond a limited amount not sufficient to permit a person to enter therethrough, comprising a part pivotally mounted adjacent the closure and adapted to be moved into a position whereby the closure rides thereover and said part engages the interior of said closure, said part being provided with a rib and projection at the end thereof, and a part mounted on the interior of said closure and provided with a cut-out portion for receiving the rib as the closure is opened and the plate engaging the projection Whereby to limit the opening of the closure.

3`. A stop for limiting the opening of a door or other closure comprising a member pivotally mounted on the floor adjacent the opening side of said door and adapted to be moved into or completely out of the path of said closure, said member having a base, a rib on the upper side of said base, said rib having a tapered end and a projection at the other end, and another member at the lower edge provided with a notch to receive the tapered end of the rib and ride over the ribv as the door is opened, said last mentioned member impinging against said projection on said first member so as to limit the opening of the door.
